How Many Tourists Visit Big Ben Annually?

Big Ben—technically the nickname for the Great Bell within the Elizabeth Tower at the Palace of Westminster—is one of the UK's most iconic landmarks. Pre-pandemic (2019), the Palace of Westminster attracted approximately 1.6 million paying visitors annually.

Note that "Big Ben" tours specifically (inside the clock tower) are limited to UK residents by advance arrangement through their MP, while international visitors can tour the broader Palace of Westminster, including the Houses of Commons and Lords. The tower's exterior and its famous chimes remain freely viewable and audible to all along the Thames.
